CassandraService

public CassandraService(com.palantir.atlasdb.util.MetricsManager metricsManager,
                        CassandraKeyValueServiceConfig config,
                        com.palantir.refreshable.Refreshable<CassandraKeyValueServiceRuntimeConfig> runtimeConfig,

                        CassandraClientPoolMetrics poolMetrics)

Method Detail

close

public void close()

Specified by:

close in interface AutoCloseable

refreshTokenRangesAndGetServers

public com.google.common.collect.ImmutableMap<CassandraServer,CassandraServerOrigin> refreshTokenRangesAndGetServers()

getCurrentServerListFromConfig

public com.google.common.collect.ImmutableMap<CassandraServer,CassandraServerOrigin> getCurrentServerListFromConfig()

It is expected that config provides list of servers that are directly reachable and do not require special IP resolution.

getLocalHosts

public Set<CassandraServer> getLocalHosts()

getRandomGoodHostForPredicate

public Optional<CassandraClientPoolingContainer> getRandomGoodHostForPredicate(Predicate<CassandraServer> predicate)

getRandomGoodHostForPredicate

public Optional<CassandraClientPoolingContainer> getRandomGoodHostForPredicate(Predicate<CassandraServer> predicate,
                                                                               Set<CassandraServer> triedNodes)

getAllNonBlacklistedHosts

public List<com.palantir.common.pooling.PoolingContainer<CassandraClient>> getAllNonBlacklistedHosts()

getRandomGoodHost

public CassandraClientPoolingContainer getRandomGoodHost()

getTokenMap

public com.google.common.collect.RangeMap<LightweightOppToken,com.google.common.collect.ImmutableSet<CassandraServer>> getTokenMap()

getPools

public Map<CassandraServer,CassandraClientPoolingContainer> getPools()

debugLogStateOfPool

public void debugLogStateOfPool()

getRandomCassandraNodeForKey

public CassandraServer getRandomCassandraNodeForKey(byte[] key)

createPool

public CassandraClientPoolingContainer createPool(CassandraServer server)

addPool

public void addPool(CassandraServer server)

addPool

public void addPool(CassandraServer cassandraServer,
                    CassandraClientPoolingContainer container)

removePool

public CassandraClientPoolingContainer removePool(CassandraServer removedServerAddress)

Removes the pool from the set of current pools. Note that this shuts down all idle connections, but active ones remain alive until they are returned to the pool, whereby they are destroyed immediately. Threads waiting on the pool will be interrupted.

cacheInitialCassandraHosts

public void cacheInitialCassandraHosts()

clearInitialCassandraHosts

public void clearInitialCassandraHosts()
